# Swayhold

A recognisable form or function persists through continual adjustment

Layer: Physics · Category: Dynamics

## Mechanism

As conditions or internal dynamics vary, ongoing adjustments contribute to keeping a form or function, and the same underlying method can make those adjustments without being replaced. Both a continuing form or function and adjustments that sustain it must be present; mere change, mere persistence, or accidental similarity across states is not an instance, and a rigid structure that withstands a disturbance without changing is not one either.

## Invariants

- A form or function continues over the interval considered.
- Ongoing adjustments contribute to its continuation.

## Failure modes

- Adjustment read as instability: visible adjustment that sustains continuity is called instability.
- Survival read as adaptation: anything that survives is called adaptive, even when no adjustment sustains it.
- Steadiness read as headroom: a form held steady by adjustment is taken to show spare capacity, when the adjustments may be close to their limit.
